Mageia

Install Flatpak
A flatpak package is available for Mageia 6 and newer. To install with DNF, run the following as root:

dnf install flatpak

Or, to install with urpmi, run:

urpmi flatpak
Add the Flathub repository
Flathub is the best place to get Flatpak apps. To enable it, download and install the Flathub repository file or run the following in a terminal:

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
Restart
To complete setup, restart your system. Now all you have to do is install apps!

Note: graphical installation of Flatpak apps may not be possible with Mageia.
